NFT GROW GUIDE THE DEFINITIVE GUIDE TO IMPROVING YOUR YIELDS USING NFT

RAISING SEEDS AND CUTTINGS IF YOU ARE GROWING FROM SEED OR CUTTINGS THIS INFORMATION WILL BE HANDY! X-STREAM AEROPONIC PROPAGATOR GROWING FROM SEED A good quality propagator provides the best environment for healthy seeds. An X-Stream Heat propagator allows you to control heat and humidity to achieve excellent results. USING COMPOST Germinate seed in a seed tray of compost. When large enough, transplant to a plastic pot with drainage holes. Plants germinated from seed are also suitable for NFT. Water as necessary. If compost contains nutrient (check the label) use water only. If compost contains nutrient use hydroponic nutrient at half strength. Plants are ready to be transplanted when you can remove the pot and the compost remains bound by the white roots of your transplants. X-STREAM HEAT PROPAGATOR USING ROCKWOOL Before using rockwool soak the rockwool overnight in water at ph 5.5. This reduces alkalinity. Plant the seed in the rockwool cube. Gently bury and cover over the seed using a blunt instrument and allow to germinate. When the seedling develops its first green leaf, begin to water sparingly with halfstrength hydroponic nutrient. WHEN TO TRANSPLANT When white roots appear it can be transplanted to a larger rockwool block. Keep seedlings watered with half strength hydroponic nutrient. Your plants are ready to be transplanted to your NFT system when you have lots of white roots visible on the surface of the large block. CUTTINGS DEVELOPED IN AEROPONIC PROPAGATORS Bring the seeds or cuttings on as directed by your propagator instructions. Young plants can then either be transplanted to an alternative medium, e.g. Rockwool, and grown on before transplanting to your system, or grown on in the propagator until the roots reach 8 10cm in length and transplanted directly into your NFT system. RAISING TRANS FROM CUTTINGS Follow the instructions for raising from seed but DO NOT use nutrients in the water until your cutting has rooted. BEFORE PLANTING OUT Add nutrients according to the manufacturer s instructions (see back page for guidance on tank volumes). Check ph. GERMINATING SEEDS IN A POT OF COMPOST A WELL ROOTED PLANT TOP TIP: For raising seedlings or cuttings, over-watering slows root growth dramatically. Always keep your plants slightly on the dry side.

PLANTING OUT AND MAINTENANCE MAINTAINING THE SOLUTION WHEN TO PLANT OUT Do not plant into your NFT system until the plant is rootbound. If white roots aren t on the outside of the growing medium when you place your plant into the NFT system the roots will become saturated with no access to oxygen and will die-back. The plants pictured below are ready for your NFT system. DO NOT transplant until your plants are at this stage. MAINTAINING ph Check ph levels in your tank weekly Decide the ph you want to maintain, between 5.8 6.5 is ideal Test the ph of the nutrient solution in your tank using a test kit or ph pen If the ph of the solution is in the correct range 5.8 6.5 do nothing If the ph of the solution is above the correct range add phosphoric acid (ph Down) If the ph is below the correct range add potassium hydroxide (ph Up) Use the ph Down or ph Up very sparingly. Adjust ph to your chosen level over several days. SAFETY FIRST Phosphoric acid is strongly acidic and potassium hydroxide is strongly alkaline. Always follow the safety instructions on the container. TOP TIP Remember a consistent temperature is key. Use a submersible heater to assist in achieving this. AEROPONIC CUTTING GRO-TANK ROCKWOOL PROPAGATION BLOCK COMPOST PROPAGATION BLOCK TOPPING UP THE SOLUTION Add nutrients according to the manufacturer s instructions. Do not let the solution level in your tank drop significantly. Use an auto-top-up to avoid this happening. WITH AN EC METER Top-up the NFT system if needed with water only, wait one hour for new water to mix with old solution, then check EC reading. Add nutrients to bring EC level back to the target EC. Empty your tank at least once per month so you can start again with a fresh nutrient solution this is called a solution change. ph-3 ph/temp 6.2 WITHOUT AN EC METER Top-up the Gro-Tank as needed with nutrient solution at half the strength of the nutrient you are currently using in the system. Empty your tank at least once per month so you can start again with a fresh nutrient solution this is called a solution change. Making up a container of half dose nutrient solution makes topping-up easier. EMPTYING THE GRO-TANK Switch the pump off. Remove the delivery tube from the channel inlet and fit the emptying tube onto the delivery tube to empty the Gro-Tank. We recommend that you remove as much solution as possible, you can use a sponge to soak up any solution that doesn t drain away. Used solution can be disposed of in the garden.

KEY THINGS TO REMEMBER ABOUT ROOTS GRO-TANK KITS RAISING TRANS FROM SEED 1. Transplant when root bound. 2. Ensure atmospheric (air space) environment is suitable for the plant you intend to grow. 3. Follow nutrient instructions on nutrient label. 4. Maintain nutrient & ph levels. 5. Monitor & control pests and diseases. THE MOST COMMON CAUSES OF POOR GROWTH 1. Plants placed in the channel too early ensure that only rootbound plants are used. 2. Heavy handedness with acid take care not to add too much. 3. Incorrect nutrient dose used check manufacturer s instructions. NFT is such an effective method of growing because it produces very healthy roots. There are three different root types; 1. PRIMARY ROOTS These are the large diameter roots which first emerge and travel into the nutrient solution and which grow very rapidly. 2. SECONDARY ROOTS These are smaller diameter roots emerging from the primary roots. The large surface area of these roots makes them vital for taking-up nutrients and water. Plants have a mechanism known as active uptake which enables plants to determine what they want to take-up from what is provided. This is why NFT is so successful for growing plants. 3. ROOT HAIRS These are vital to the health of your plants. Root hairs are the lungs of the plant. They take-up oxygen (as essential to plants as it is to humans), which is why your plants need to have root hairs above the solution level in the channel.
